My cat has a lump on its neck or chest. What should I do next?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Male | neutered | 11 lbs

My cat seems to have a bomb under the neck near his chest area. I showed a pic of it to a friend who studies to be a vet and said it could be a tumor or neoplasia. What is next if this is the case?

The next step is to take Foffy into the vet to have this lump examined. It could be a malignant tumor, but it could also be a cyst or a benign tumor. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options with you. I'd make an appointment with the vet for Monday. Good luck, I hope this helps!

I’ve noticed a lump on Misty, my cat’s, chest near the top of her front left leg. I can feel it through her fur and it’s roughly the size of a grape. I’m worried it may be something serious.
In a cat Misty's age, there is always a chance any lump is malignant. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give her vet a call to make her an appointment.

Hi I noticed my cat has a hard, callus-like, pink lump on his chest. I have no idea what it is and I’m very worried!
Thanks for using Boop by Petco! This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good night!

My cat has a small bump akin to a human mole where her shoulders are. She doesn’t seem bothered when we touch it or examine it. However, it is new. Should I be concerned?

My cat has a lump on the right side of chest since 2 days.but he is eating right.there is no change in his deit.what can be the reason of the lump
Thank you for submitting your question regarding Pillu. I recommend that he sees his veterinarian for an examination and a procedure known as a fine needle aspirate. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will help to diagnose the mass. He could have an infection under the skin, a benign growth or even skin cancer. Based on these results, treatment can be started if needed. I hope this information helps!

She has a small, hard mound just below her chin. It seems to have appeared over night. I should take her to the vet right?

Hi as you can see from the attached photo, my cat has a soft-ish lump on her back. It's white with some visible veins on it. I just wanna know if its potentially dangerous or not? (Ive been poking the lump and she is not in any pain whatsoever)
Unfortunately in a cat Toy's age, there's a chance any lump could be malignant. It could also be benign or a cyst. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I'd take her into a vet today to get this checked out. Best of luck.

My cat has a big bump by his neck, should I be concerned? It doesn’t seem to bother him when we touch it.

I'm sorry Bebe has a lump, but this is a great question! The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would speak to your vet about having this done on Bebe's lump if they feel it's necessary. I hope this helps :-)

Hello, My cat has a ball of skin hanging from the bottom of his head, under the lower jaw. What is it? And is it removable?
This could be a growth and in a cat Laurence's age, this could be malignant. It may be able to be removed, but I can't say it for certain without seeing him in person. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call in the morning to make him an appointment. I hope this helps!

I just discovered a large lump on the front side of my cat and it just appeared today. What could it possibly be? He is around 8 years old, and can't seem to keep weight no matter what we try.
